Patent DE-2338149-A1 (DE)
Title: Bypass valve of hot water central heating boiler - has static and dynamic pressures acting on it balancing each other
Inventor: KOHL WALTER
IPC: F24D19/10
Filed: 1973-07-27
Abstract: A pump circulates water through a heat exchanger and room heating units. A pressure relief valve is arranged in a bypass between the flow and return connections of the pump. As room heaters are shut off, the flow falls, the pump discharge pressure rises and the relief valve opens to maintain circulation through the pump and heat exchanger. The extent to which the valve opens depends on the dynamic pressure and thus the water velocity through it. To maintain constant flow the valve and piping are so placed geometrically that changes in dynamic pressure are balanced by compressing changes in static pressure.

The space between the hinge points on the frame form the base of an isosceles triangle, in which first the base is thermally expanded so that the shadow mask moves away from the screen phosphor layer. In operating conditions the metal strips are also thermally expanded which initiates a movement of the shadow mask towards the screen.

Title: Measurement method of an object selected dimension - has an electric test sensor generating a signal representing the object dimension
Inventor: PORTER WALLACE MILTON
IPC: B24B49/04
Filed: 1973-10-12
Abstract: This signal is generated when the object is in a test position with respect to the sensor, and a false signal is generated when the object is in a different position. Relative movement of the object and sensor is produced, so that the object passes through the test position, when a test position signal is generated. The sensor output is evaluated only when this signal is present. The sensor is stationary, and the object is moved past it. A control signal, depending on simultaneous presence of the test position signal and the sensor output signal, is generated, representing the object dimension.

Title: Black and white television picture with three dimensional effect - involves oscillation of cathode ray tube voltage to regulate colour definition
Inventor: ROEDER ERNST
IPC: H04N11/00
Filed: 1974-08-23
Abstract: An improvement in the colour definition of black and white television reproduction is effected by applying an oscillator control to the cathode ray tube voltage. The oscillating voltage cycle results in alternating acceleration and retardation of electrons and the resulting picture is given a three-dimensional effect with improved colour definition. The colour sensitivity is a function of the oscillation frequency. The control action is synchronised with the picture frequency in order to generate a suitable voltage and the wavelength defines the tone. The screen of the black and white cathod ray tube is covered with a phospor such as is normally used in black and white television sets.
